Hi Mohsin,

That's really not so much information so it's hard to help much.

If you're using Ethernet make sure you set:

    netif->output = etharp_output;
    netif->output_ip6 = ethip6_output;
#endif /* LWIP_IPV6 */

and make sure netif->linkoutput is set too.

For incoming packets try to capture an interrupt from your Ethernet controller and debug the path the packet takes.

Hi Ivan,
I'm new to IPv6 and trying to implement it in my device and have called
netif_create_ip6_linklocal to form IP6 address of my device.
But when I connected it to my PC, I couldn't find any packet in Wireshark originating from my device. I also confirmed through some debug messages
that my device is writing some packet to write FIFO but no packet is
received at PC.
Also I discovered that nd6_input is not being called any time in my case.
Please suggest some solution.
